I have papershells in my forage fish pond that has lots of discarded broken sidewalk cement pieces along most of the shoreline. I do not see any evidence of crayfish burrowing in the pond on the slopes except for the few Cambarus crayfish that invaded from the creek. I am pretty sure the abundant crayfish reside under the pieces of broken. When occasionally moving the cement pieces I see crayfish move out. This pond periodically gets drawn down 2-4 ft for various reasons so burrows / holes in the basin would be apparent. The Cambarus/Procambarus spp. move out of the pond and make burrows often the burrows have chimneys.
